Condom having improved functionality

ABSTRACT

A condom is configured to include a space such that a front glans part of the condom does not excessively come into contact with the penis of a man by selecting a material having moderate elasticity such as soft synthetic resin or synthetic latex rubber or a foamed rubber material conforming thereto or the like for the front part of the condom made from a soft rubber material; and includes embossed sponge layers or fine soft hairs additionally laminated on the inside and outside of the condom, to provide an excellent moisturizing effect such that an excellent contraceptive effect and a sexual pleasure-increasing effect can be simultaneously obtained when a user wears the condom, thereby providing multiple effects such as contributing to the treatment of patients with chronic dyspareunia or patients with anorgasmia and the like.

REFERENCE TO RELATED APPLICATIONS

This is a continuation of pending U.S. application Ser. No. 14/641,504,filed on Mar. 9, 2015, which is a continuation-in-part of InternationalPatent Application No. PCT/KR2013/002415, filed on Mar. 22, 2013, theentire contents of which are incorporated herein by reference.

BACKGROUND OF THE INVENTION

The present invention has been devised for the purpose of avoidingpersonal or social criticism and waste due to undesired pregnancy byimproving a structure of male condom and thus further encouraging thepublic use of the condom and of further enhancing a functionality of thecondom by providing a woman with a sexual anesthesia treating effect anda man with an effect of prevention of impotence, premature ejaculationetc. by mixing a suitable amount of vasodilators with jelly liquid forpackage of the condom and thus increasing sexual pleasure in the use ofthe condom.

For a structure of the condom generally used up to now, a main body partof the condom is mainly made of natural latex or artificial latexmaterial having excellent flexibility and elasticity as can be seen inFIG. 5 or patent document 1 of prior art (Korean Registered UtilityModel No. 20-0356020), and a constricting ring—which is circular elasticbody or annular ring body and the like—is provided at a rear inlet, andlubricant jelly is applied on both inner and outer surfaces of thecondom and then the condom is individually packed and thereafterdistributed as a product.

However, such a conventional condom has problems that its surfaceconsists of only simple smooth surface and thus the jelly tends to bedried in the use of the condom, and in particular, when secreting liquidof a female partner side is insufficient, surface lubrication isinsufficient and thus friction force increases, accordingly, the femalepartner suffers significant vaginal pain, and in a sever case, a slightdamage of vaginal wall may be caused.

Induction of the vaginal wall pain due to such insufficiency oflubricity reduces an original primary contraception function of thecondom and thus makes the use of the condom avoided.

In addition, when the conventional generally-used condom is worn, apenis of the man and an inner surface of the condom completely closelycontact with each other; therefore, the sexual pleasure effect felt bythe male partner considerably decreases, which also makes the man avoidthe use of the condom.

The present invention aims at providing a new structure of the condomwhich fundamentally eliminates the structural defect that both of themale and female partners suffer and thus, for the man, avoids thereduction of sexual pleasure due to excessively close contact with thecondom and for the woman, fundamentally avoids disease damage orreduction of sexual pleasure due to the drying of the vaginal secretingliquid and the friction.

SUMMARY OF THE INVENTION

In view of the background art described above, the present invention hasan object of obtaining a lubricant moisturizing and sexual pleasureimprovement effect resulting from a frictional force reduction effect ofcondom itself by widely and largely forming a front glans penis portionof the condom and also adding uneven spongy layer having a goodelasticity or soft fine hairs (downy hairs or very minute and softhairs) to inner and outer surfaces of the condom for improving a commonstructure of a condom made of soft rubber film material whose inner andouter surfaces consist of only simple smooth surface, and an objects ofensuring the above-mentioned various functionalities by substitutingjelly liquid for a package of the condom with a functional jelly liquidhaving an effect of enlarging the blood vessels and thus promoting thecirculation of the blood over the entire surface of the vaginal wall insexual intercourse while ensuring lubricity of the jelly liquid in theuse of the condom.

To achieve the above objects, the present invention can simultaneouslyachieve both excellent contraception effect and sexual pleasureimprovement effect in the use of the condom by forming a space so that afront glans penis portion of the condom does not excessively closelycontact with the male penis and additionally laminating, as moisturizingmeans having an excellent moisturizing effect, uneven spongy layers orfine hairs made of suitable elastic material such as soft syntheticresin or synthetic latex rubber and similar foamed rubber material andthe like, on inner and outer surfaces of conventional condom made ofsoft rubber material.

Furthermore, the present invention can induce appropriate enlargement ofperipheral blood vessels distributed in a contact portion between thefemale vagina and male penis in the use of the condom to significantlyenhance the sexual pleasure in the use of the condom by mixing asuitable amount of vasodilators widely used as anti-impotence drug suchas Viagra with the jelly liquid provided inside a package of the condom.

The condom of the present invention has the following functionaleffects:

Since the surface of the condom has the uneven spongy layers or finehairs having a good moisturizing effect, the lubricant of the condom orfemale vaginal secreting liquid is not easily dried in the use of thecondom is worn, and thus the sexual intercourse itself is smoothly doneand the sexual pleasure is significantly enhanced.

Since the uneven spongy layer or fine hairs having a good flexibilityand elasticity is selectively doubly formed on the entire surface of thecondom, the man or woman can feel very good sexual pleasure and thuseasily reach the orgasm, which is also helpful to sound and healthysexual life.

The moisturizing effect and sexual pleasure enhancement effect promotethe secretion of the female vaginal liquid, thereby contributing totreating patients with dyspareunia or sexual anesthesia.

In the case of the man, since the condom does not excessively closelycontact with a front portion of the penis and a certain space is formed,the touch felt by the glans penis in the use of the condom is keen as ifthe penis directly contacts with the vagina, whereby a conventionaldisadvantage is avoided that the sexual pleasure is reduced in the useof the condom.

By mixing a suitable amount of the vasodilators with the jelly liquidaccommodated in a package of the condom, capillaries in a contactportion between the vagina and penis are locally enlarged in the use ofthe condom, thereby significantly increasing the sexual pleasure, andaccordingly, an effect is obtained that female disease such as sexualanesthesia, colpoxerosis and dyspareunia can be effectively preventedand treated and male urological disease such as impotence, prematureejaculation, reduction of sexual pleasure etc. can be also treated,while reliable contraceptive function is exhibited, and in particular, apositive effect can be expected that the phenomenon of avoiding thecondom is changed to preference of the use of the condom, therefore, thepresent invention can be said to be a very useful invention.

DETAILED DESCRIPTION OF THE INVENTION

In a case of a conventional condom (1) generally used up to now, a mainbody (2) is made of material such as natural latex or soft syntheticrubber and the like, and a constricting ring (3) is formed at a rearinlet, as illustrated in FIG. 7. Such an existing condom (1) has asurface part consisting of simple smooth surface.

The present invention is intended to improve a functionality of such anexisting condom (1) by internally and externally coating moisturizingmeans (S) which holds a large quantity of lubricant applied to thecondom (1) and thus has a moisturizing function as illustrated in FIGS.1 to 5.

The condom (1) of the present invention is made of soft material such asnatural latex or synthetic rubber etc. by a known method, with aconstricting ring (3) provided at a rear portion of main body (2). Inthe present invention, a front glans penis portion (A) of the condom (1)is widely and largely formed so that a certain space (6) sufficientlyremains inside the front glans penis portion in order that the maleglans penis is spaced apart from an inner surface of the front glanspenis portion of the condom (1) even while the male glans penis isinserted and erected in the front glans penis portion of the condom.

As the moisturizing means (S) formed on the inner and outer surfaces ofthe condom (1) by coating, uneven spongy layers (4 a, 4 b) of the samematerial as the main body (2) are formed on the inner and outer surfacesof the condom (1) by coating as illustrated in FIGS. 1 to 3, or softfine hairs (5 a, 5 b) of the same material as the main body (2) areformed on the inner and outer surfaces of the condom (1) by coating asillustrated in FIGS. 4 and 5.

The uneven spongy layers (4 a, 4 b) or fine hairs (5 a, 5 b) areproduced from natural latex or synthetic rubber unharmful to a humanbody. It is preferable that the uneven spongy layers (4 a, 4 b) areformed with a porous structure by finely foaming the material.Alternatively, the uneven spongy layers (4 a, 4 b) is made in the formof sheet and then adhered to the entire outer surface of the condom (1)or inner surface of the frond glans penis portion (A) of the condom (1).

The uneven spongy layers (4 a, 4 b) may be integrally adhered byseparately preparing injection molds and injecting foam resin to theentire outer surface of the condom (1) or the inner surface of the frontglans penis portion (A) of the condom (1) in an insert molding manner asillustrated in FIG. 6. The injection structure in FIG. 6 illustrates anexample where the uneven spongy layer (4 a) is coated on the entireouter surface of the condom (1) coupled with a core. Although notillustrated, when the uneven spongy layer (4 b) is to be coated on theinner surface of the glans penis portion (A), the uneven spongy layer (4a) is coated on the outer surface of the condom (1) as illustrated inFIG. 6 and then is hardened, and thereafter is turned inside out andthen coupled with the core, and thereafter the injection is performed inthe insert molding manner.

Furthermore, the spongy layers (4 a, 4 b) having irregular unevenstructure may be coated on the outer or inner surface of the condom (1)according to another method by spraying resin liquid onto the surface(spray depositing method).

The uneven spongy layers (4 a, 4 b) are formed of the same material asthe main body (2) of the condom (1) or similar material. Surfaces of thespongy layers (4 a, 4 b) consist of spongy structure that is a fineporous structure, and the fine hairs (5 a, 5 b) are also produced fromthe same material as the main body (2) of the condom (1) or similarmaterial and are densely formed, and therefore, have a good moisturizingeffect of holding the lubricant applied to the condom (1) or femalesecreting liquid in the use of the condom and exhibit soft touch.

Therefore, when the condom (1) is worn, the outer uneven spongy layer (4a) or outer fine hairs (5 a) on the outer surface of the main body (2)imparts lubricant friction effect and thus very soft touch when rubbingagainst the female vaginal wall, and serves to adequately enhance thesexual pleasure depending on the use of the condom.

In addition, the uneven spongy layer (4 a) has an excellent moisturizingeffect due to its own porous structure, and the fine hairs (5 a) have anexcellent moisturizing effect due to its dense structure. Therefore, theuneven spongy layer and hairs have an effect that the vaginal secretingliquid is maximally prevented from being dried and the damage of thevaginal wall or the induction of pain is prevented.

Furthermore, the certain space (6) remains inside the front glans penisportion (A) of the main body (2) of the condom without the front glanspenis portion closely contacting with the erected male glans penis, andthus the inner uneven spongy layer (4 b) or inner fine hairs (5 b)formed on the inner surface of the glans penis portion (A) generatesirregular friction on the male erected glans penis to continuouslyimpart sexual stimulation to the glans penis where peripheral nerves areconcentrated. Therefore, even with the condom (1) worn, the male usercan feel a good sexual pleasure as if his penis directly rubs againstthe vaginal wall.

Such an operational effect obtained by the configuration of the condom(1) according to the present invention can greatly contribute toincreasing the sexual pleasure for the man as well as woman. Such sexualpleasure-increasing effect and the moisturizing effect of the lubricantand female secreting liquid have a functional effect that a phenomenonof avoiding the use of the conventional condom (1) can be fundamentallyeliminated. Furthermore, the condom of the present invention can bewidely used as an original contraceptive device for preventing undesiredpregnancy, and an additional effect of healing the dyspareunia or sexualanesthesia etc. can be simultaneously obtained as a user prefers the useof the condom (1) thanks to the sexual pleasure-increasing effect.

Furthermore, according to the present invention, the condom (1) may beaccommodated in a sealed package (10) while the condom is immersed inlubricant jelly liquid (20), as illustrated in FIG. 8. By mixing asuitable amount of the vasodilators with the jelly liquid (20)accommodated in the package (10) of the condom (1), capillaries in acontact portion between the vagina and penis are locally enlarged in theuse of the condom, thereby significantly increasing the sexual pleasure.Accordingly, an effect is obtained that female disease such as sexualanesthesia, colpoxerosis and dyspareunia can be effectively preventedand treated and male urological disease such as impotence, prematureejaculation, reduction of sexual pleasure etc. can be also treated,while reliable contraceptive function is exhibited, and in particular, apositive effect can be expected that the phenomenon of avoiding thecondom is changed to preference of the use of the condom. Therefore, thepresent invention can be said to be a very useful invention.

The condom is accommodated in the sealed package (10) with theconstricting ring at an opening side rolled up and the entire condom (1)is packed while it is sufficiently immersed in the lubricant jellyliquid (20) contained together. Therefore, when the condom is used, itis worn on the male penis with the jelly liquid (20) applied on thecondom, and accordingly, the jelly liquid (20) contacts with outercircumferential surface (C) of the male penis and inner circumferentialsurface (B) of the female vagina and thus imparts good lubricity.

The present invention has a characteristic that the vasodilators ismixed with the jelly liquid (20) (lubricant) and when the jelly liquid(20) contacts with skin surface of the vagina in the use of the condom,the vasodilators enlarges capillary arterial vessels, thereby allowingthe blood to smoothly circulate.

For the vasodilators mixed with the jelly liquid (20) of the presentinvention, various medical components may be selectively used whosesafety has been clinically and widely verified.

In addition, citric acid sildenafil which is a main component of Viagra(trade name) that is a kind of anti-impotence drug, tadalafil which is amain component of Cialis (trade name), udenafil which is a maincomponent of Zydena (trade name) and the like may be mixed in liquid orpowdery form.

a mixing amount of the vasodilators used may be appropriately adjustedin the range of 1 to 10 part by weight with respect to 100 part by weighof the jelly liquid.

The vasodilators are mainly orally dosed. However, in the case of thepresent invention, if the vasodilators contacts with the female vaginalwall or circumferential skin of the male penis where peripheral bloodvessels are developed, the solubility of the vasodilators is furtherincreased by body temperature and components of drug liquid deeplypenetrate inwards through skin cell membranes or pores to reach thecapillary and then be absorbed into the blood by osmotic pressurephenomenon.

The vasodilators thus reaching the capillaries in the penis directlystimulates and enlarges the capillaries, and accordingly, the flow ofblood, i.e. the circulation of capillary blood is promoted to be smooth;therefore, an effect is obtained that male erection power is increasedand female sexual pleasure is remarkably enhanced.

That is, the increase of sexual pleasure provides a synergy effect offurther promoting secretion of vaginal mucus by further stimulatingfemale sexual nerves. Furthermore, the enlargement of blood vesselsprovides the man with a positive effect that it increases sexual desireto enhance the erection power and delays the ejaculation to prevent thepremature ejaculation.

Therefore, using of the condom of the present invention provides anadditional effect that the man can exhibit a good penis erectionfunction even without taking the orally-dosed anti-impotence drug suchas Viagra.

The present invention has been devised for the purpose of avoidingpersonal or social criticism and waste due to undesired pregnancy byimproving a structure and functionality of male condom and thus furtherencouraging the public use of the condom, and thus has industrialapplicability.
